I have been utterly disappointed by the quality of reproduction decals that are out there. I'm an Art Director of 30 years, so quality of font usage, layout, and print quality mean A LOT to me. Some here may remember years ago (2015-ish?) that I reproduced the yellow Oshawa posi sticker. I have had further success finding and reproducing the Engine Coolant sticker and the Early and Late versions of the L34 with 4speed emissions/tuning stickers (coded DP & AR).
This jacking instructions decal is also on my list. It took me a couple weeks of evening work to completely REDRAW the illustrations, match the fonts EXACTLY, and to do the layout. I'm 99% complete on this and will be getting it printed soon. If you want dead-nuts-correct reproduction, better than anything that out there, drop me a PM and we'll talk. I have a bunch more reproductions in the works: DG & CO "Keep you GM Car..." air cleaner decals, BC & EZ tire pressure decals, engine suffix decals for valve covers, to name a few.
